I just tried tailscale in the last month and it will now be my preferred way to access my services outside of my network.

The ability to read, and maybe watch a video. And then persistence for some of the trial and error you will run in to. All skills you need can be picked up with the above.

I turn mine off to save power when I’m not actively using it. I have a small 65 watt server that stays on all the time. Currently it has been up for 3 months or so.
